System Calibration Calibration
4 - 44 046-006272-00 A7™ Service Manual
[00 00 00 40] is displayed.
Measurement range error occurs to the
PEEP pressure sensor.
1. Check the tube and air-tight connection.
2. Check the supply gas pressure.
3. Check the settings of the calibration
device.
4. See section 5.4 (pg. 5-71) "Sensors and
Valves Problems".
5. Replace the board.
[00 00 00 80] is displayed.
The calibration data of the airway
pressure sensor is not unidirectional.
1. Check the tube and air-tight connection.
2. Check the supply gas pressure.
3. See section 5.4 (pg. 5-71) "Sensors and
Valves Problems".
4. Replace the board.
[00 00 01 00] is displayed.
The calibration data of the PEEP
pressure sensor is not unidirectional.
1. Check the tube and air-tight connection.
2. Check the supply gas pressure.
3. See section 5.4 (pg. 5-71) "Sensors and
Valves Problems".
4. Replace the board.
[00 00 02 00] is displayed.
Resolution error occurs to the airway
pressure sensor. (The difference
between the maximum AD and the
minimum AD is less than or equal to
500AD. When the difference between
one point and its previous pressure
value is greater than or equal to 1
cmH2O, the resolution is less than 1cm
H20 ~2AD).
1. Check the tube and air-tight connection.
2. Check the supply gas pressure.
3. Check the settings of the calibration
device.
4. See section 5.4 (pg. 5-71) "Sensors and
Valves Problems".
5. Replace the board.
[00 00 04 00] is displayed.
Resolution error occurs to the PEEP
pressure sensor. (The difference
between the maximum AD and the
minimum AD is less than or equal to
500AD. When the difference between
one point and its previous pressure
value is greater than or equal to 1
cmH2O, the resolution is less than 1cm
H20 ~2AD).
1. Check the tube and air-tight connection.
2. Check the supply gas pressure.
3. Check the settings of the calibration
device.
4. See section 5.4 (pg. 5-71) "Sensors and
Valves Problems".
5. Replace the board.
[00 00 08 00] is displayed. The output pressure of the valve is low.
1. Check if there is enough gas supply for
the whole calibration process.
2. Check if the maximum output pressure of
the PEEP valve is more than 90 cmH2O. If
not, replace the airway module.
[00 00 10 00] is displayed. The change of flow is not unidirectional.
1. Check if the sampling line is properly
connected.
2. Replace the board.
[00 00 20 00] is displayed.
Communication with the calibration
device is interrupted.
1. Check the connection between the
calibration device and communication
cable.
2. Replace the calibration device and then
perform calibration again.
[00 00 40 00] is displayed. The system fails to write EEPROM.
1. Perform calibration again.
2. Replace the monitoring board.
[00 00 80 00] is displayed. ACGO switch is on "ON" position.
1. Check if ACGO is positioned to "OFF".
2. Check the ACGO identification switch.
[00 01 00 00] is displayed.
The resolution of the valve is not
enough.
1. Check if there is enough gas supply for
the whole calibration process.
2. Check if the calibration device works well.
3. Replace the PEEP valve.
